Items
On several levels there are items which can be used to gain an advantage over your opponents. For example, in the Christmas Tree level get the battery then go to the tank. Press Attack and wail on your opponents with some serious firepower. In Joyride, you must get the matches on top of the police car. You can now use the propane torch in the same manner. In Spacewalk, use the lever found in the main pod of the space station to fire the thrusters and send your opponents into deep space. In Club Bano and Jeffery's Kitchen, look for a switch on the wall to start the fan or garbage disposal respectively.
